Application filed November 18. 1912. Serial No. 731.984.

To (Ind/17107774; may concern lle it known that I, vl lnrinnn S. LIVEN-noon, a citizen of theUnited States, residing at Kansas City, in thecounty of Jackson and State of Missouri, have invented certain new anduseful Improvements in Mechanical .lllovements; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilleil in the art to which it appertains tomake and use the same, reference being had to the acccanpanyingdrawings, and to the letters and figures of reference marked thereon,which form a part of this specification. 1

My invention relates to a lllGCl'llDlCiLl nnwement, and moreparticularly to a toggle mechanism especially adapted for use inconnection with the plunger head of a baling press, or like device, theprincipal ob ject of the invention being to secure a compound leverageon the plunger head or driven member.

it is also an object of the invention to provide the improved details ofstructure here inafter described and illustrated in the acconu ianyingdrawings, wherein.

Figure I is a perspective view of a mecl'uinieal movement constructedaccording to my invention, a part of the carrying frame being removedforbetter illustration. Fig. ll is a side elevation of a part ofthe1nechauism and the case within which it is inclosed. Fig. III is alongitudinal, vertical sectionof the movement as it appears when theplunger head is in its back position. Fig. IV is a view of the sameparts with the plunger head advanced.

Referring more in detail to the parts: 1 iflesignates a frame withinwhich the movement may be mounted, the frame here shown representing thebaling case of an ordinary hay press Extending through slots 2, on

opposite sides of the frame 1, so as tohave both sliding and pivotalmovement therein, is an axle 3, having anti-friction rollers 4 on itsouter ends adapted for travel within the. lotted bearings5 which arerigidly fixed to the outer faces of the frame sides. Pivotally mountedon the axle 8, and adapted for reciprocatory travel therewith, is acrank member 6, onearni of which has an elongated slot 8 radial with theaxle and through which a roller 9, journaled near the lower edges of thesides of the frame is pro jected to limit the reciprocatory travel, ofthe crank and serve as a fulcrum on which the crank may turn. A secondarm 10 of said crank is phxotally connected witlnthe links 11, which arein turn pivotally inounted on a cross rod 12, carried by the plunger 13,in substantially the same horizontal plane as the axle 3. The plunger 13may he of any suitable c n striuztion., but preferably comprises; sidemembers 'l lha vinp; slots 15 thrruredi w rich the crank axle 3 isprojected to guide the plunger during its reciprocatory travel, underinfluence of the crank, I also prefer to provide the axle i-l withanti-friction rollers 16 over which the slotted portions of the plungermay travel, and provide the plunger with rollers 17 which are adaptedtotravel on the bottom of the case in order to facilitate the travel ofthe plunger. One endof a pitnian 18 p ol'ally connected witha third arm1?) of the crank (3, preferably by a pin 20 which extended through anaperture fit in said arunthe opposite end of the pitinan beingeccinitrieally" connected with a large gear wheel 22 which is carried onstub shaft 52?; on the frame 1 and driven from a pinion 2 1, which mayreceive its power from any suit able source.

In using the movement.

, presuming the parts to be constructed and assembled as do} smiled, andassociated with an. ordinary hay press, or other mechanism with whichthe movement may be used, when power is ap plied to the pinion il -fl,the pitniau 18 is op crated to rock the c 'ank arm 19 upwardly andthereby ailvance the crank arm ll). llllhcn the crank arm 10 isadxeinced the toggli-i link 11 is straightened and forward the plungerhead during the 'l.orward move; ment of the pituian, it being apparentthat when the arm 10 assumes a horizontal position the toggle link willalso be horizontal, owing to the fact that the pin 12 is made to travelin substantially the same horizontal plane as the axle 3, It is apparentthat, if the crank member were allowed to recur)- rocate freely, theplunger would be ad vanced only for a distance equal to the horizontalstroke of the pitman, but that by reason of the pivotal. engagement ofthe arm 8 with the roller 9, the crank is turned as it is forwarded, sothat the arm 10 and links 11 are forced to their horizontal orstraightened relation, thereby lengthening the stroke of the plunger. Asthe pitman returns from its forward position it exerts a pull on thecrank arm 19 tending to retract the arm and at the same time pivotingthe crank: on its roller bearing, so that as the crank is movedbackwardly the arm 10 is raised and breaks the toggle like connectionbetween the arm 10 and link 11 until when the pitman is at its rearlimit the link is in nearly a perpendicular position (Figs. I and III).

It is apparent that with the mechanism described, a compound leverage ortoggle movement is provided through the reciprocatory drive of the crankfrom the pitman and also because ofthe pivotal movement of the crank onits roller fulcrum. It is also apparent that the length of stroke andthe leverage on the crank may be varied by changing the position of thepitman on the arm 39. so apparent that having the pitman eccentricallyconnected with the crank the links 11 are always in motionstraighteningon the advancing movement and breaking on the back travel of the plungerso that the plunger is actuated simultaneously by the reciprocatorymovement and by the toggle action. It is also ap parent that with thepitman and fulcrum arms of the reciprocatory crank arranged as shown,the fulcrum point of the crank recedes from its axial center as theplunger is advanced, thereby providing an increased leverage at thepoint where the greatest power is required.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent is 2- 1. In a mechanical movement, adriven member and an axle adapted for reciprocation in the samelongitudinal plane, a transmission element pivotally mounted on theaxle, and provided with arms, one of which is operatively connected withthe driven member, a driver operatively connected with a second arm ofsaid element, and a fulcrum member slidably engaged by a third arm ofsaid element.

2. In a mechanical movement, the nation with a frame having slots inposite sides, of an axle adapted for guided travel in said slots, acrank member carried by the axle, driving and driven members eclt iscombilts op- Gopies of this patent may be obtained for five cents each,by addressing the centrically connected with said crank member, and afulcrum adapted for sliding contact by the crank member, for the purposeset forth.

3. In a mechanical movement, the combination with a frame havingparallel slots in its opposite sides and having guide rails adjacentsaid slots, an axle adapted for travel in said slots and having rollerscontacting the guide rails, a crank member mounted on the axle, drivingand driven membershaving eccentric link connection with the crankmember, and a stationary fulcrum adapted for sliding contact by thecrank member, for the purpose set forth.

i. In a mechanical movement, an axle adapted for reciprocation in afixed path, a transmission element pivotally mounted on the axle andhaving radial arms, one proided with a radial slot, a stationary fulcrnm inclcsed by the slot, and driving and driven members having pivotalconnection with other of said arms.

In a mechanical movement, the combination with driving and drivenmembers and a fulcrum, of an oscillatory and reciprocatory elementhaving a fulcrum engaging member and having eccentric connection withboth the driving and driven members whereby the driven member isactuated by either the oscillatory or the rcciprocatory movement of theelement independently of each other or by both simultaneously.

(5. In a mechanical movement, a Y-shaped member having central pivotalmounting and having a slot in one of its arms, a stationary fulcrumprojected through the slot and adapted for sliding contact by the armthrough which it is projected, a plunger having link connection with asecond arm and. a revoluble driving member having pit man connectionwith a third arm whereby reciprocatory and oscillatory movement of theY-shaped member is induced to reciprocate the plunger, substantially asset forth.

In testimony whereof I affix my signature in presence of two witnesses.
